The i-stop yellow light on the Atenza staying on is a normal phenomenon. Below are specific details about the Atenza: 1. Configuration: The new vehicle comes standard with features such as the intelligent idle stop system and brake energy recovery system. The Atenza 2.5L model accelerates from 0 to 100 km/h in just 8.3 seconds, with a combined fuel consumption as low as 6.9 liters per 100 km, while the 2.0L model achieves a combined fuel consumption of only 6.3 liters per 100 km. 2. Exterior: The vehicle adopts Mazda's KODO design philosophy, featuring a U-shaped front grille paired with LED headlights for a more sporty appearance. The new model introduces an 11-speaker sound system. Compared to the previous generation Mazda6, the Atenza's wheelbase has been increased by 115mm, providing more spacious rear seating. The Atenza utilizes the SKYACTIV chassis technology, equipped with a high-performance MacPherson strut front suspension and a multi-link independent rear suspension. Through structural optimization, it achieves both weight reduction and increased rigidity.

I remember last year when I was driving the Atenza, the i-stop yellow light kept coming on, which was quite annoying. This yellow light staying on indicates a malfunction in the start-stop system, usually due to an aging battery, because i-stop requires strong electrical power to allow the engine to start and stop frequently. If the battery is weak, it easily triggers a warning. That time, I found out the battery needed replacement, so I immediately went to the shop and got a new one, which fixed the issue. Additionally, if the weather is too cold, the system automatically disables itself, and the light may stay on for a while, possibly returning to normal once it warms up. If the light stays on continuously, don’t delay—check the battery or sensor issues before driving. Otherwise, if the car stops at a traffic light, the engine might shut down and fail to restart, leading to a safety hazard. It’s advisable to regularly monitor the battery condition during maintenance and not wait until it completely fails before fixing it.

What is the normal tire pressure range for highway driving?

According to the international GBT2978-2008 standard requirements, the standard tire pressure for highway driving is 2.4-2.5bar for standard tires, and 2.8-2.9bar for reinforced tires. The maximum pressure should not exceed 3.5bar. The hazards of excessive tire pressure are as follows: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting other components' longevity; Overextends tire cords, reducing elasticity and increasing driving load; Decreases puncture resistance, making tires more vulnerable to sharp objects like nails or glass, potentially causing internal cracks, blowouts, or tire bursts. Insufficient tire pressure increases friction with the road surface, leading to heavy steering, increased fuel consumption, and deviation, all detrimental to driving safety; Excessive movement of tire components causes abnormal heat generation; Weakens cord and rubber functionality, leading to delamination, cord breakage, or rim friction damage; Multiplies ground friction, rapidly raising tire temperature and softening rubber, drastically reducing strength - potentially causing blowouts at high speeds; Increases tire body deformation, causing sidewall cracks and flexing that generates excessive heat, accelerating rubber aging, cord fatigue, and tread shoulder wear.

How to Set Up LuckyCam Dash Cam?

Dash cam setup instructions are as follows: Resolution: Most dash cams offer four resolution options: 1080FHD, 720P, WVGA, and VGA. For memory cards below 8GB, 720P is recommended; for 16GB and above, 1080FHD can be selected. For daily urban use, set to 1080FHD to capture more detailed footage. For long-distance driving, 720P is recommended to extend recording time and avoid mid-journey video overwriting. Loop Recording: Most dash cams offer three duration options for segmenting videos: 1 minute, 2 minutes, and 3 minutes. A 2-minute segment is generally the most suitable. Audio Recording: Dash cams record both road sounds and in-car audio. If privacy is a concern, this feature can be turned off to prevent potential privacy leaks and unnecessary issues. Motion Detection: With motion detection enabled, the dash cam automatically records when movement is detected, typically with a 2-5 second delay. However, it's not recommended to use this feature while driving due to sensitivity and algorithm issues, which can cause significant frame loss.

What to Do If You Get a Parking Ticket in a Parking Space?

The parking space may have markings but is not recognized by traffic authorities; the parking space has time restrictions; the parking space has specific requirements for vehicle orientation (e.g., parking in the wrong direction); the vehicle is not entirely within the marked lines (e.g., over the line); some special parking spaces may have vehicle type restrictions. If none of these five situations apply, you may consider appealing the penalty. Before appealing, pay the fine first, then visit the local traffic division to understand the violation details, such as reviewing surveillance footage to check if the enforcement was ambiguous. This can help with a successful appeal. Before applying for a review, make copies of your ID card and the penalty decision (no need to copy your driver's license). Bring the originals and copies to the relevant office. When filling out the administrative reconsideration application, clearly explain the source of the violation. If you have video or third-party evidence, it will be helpful. After submission, wait patiently for the result. The reviewing authority (either the local public security agency or the higher-level traffic management authority) must issue a ruling within five days of receiving the appeal.

What Causes a Sudden Change in Car Horn Sound?

Car horn sound suddenly changes due to weather conditions or horn damage. Below are detailed explanations for the sudden change in car horn sound: Weather Conditions: Due to weather conditions, the rubber of the horn may harden, leading to a change in sound. This issue is relatively normal, and as temperatures rise, the horn sound will return to normal without any need for concern. Horn Damage: Damage to the horn relay, horn contacts, or the horn's power supply circuit can all cause changes in the horn sound. The car horn is an audio signal device in vehicles. While driving, the driver can emit necessary signals as required or regulated to warn pedestrians or other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. The car horn used in vehicles produces sound through the vibration of a metal diaphragm.

Can Tesla Get Blue License Plates?

Tesla vehicles cannot obtain blue license plates as they are classified as new energy electric vehicles and are only eligible for green license plates. Below is an introduction to Tesla: Body Dimensions: Taking the 2021 Model Y as an example, the vehicle measures 4750mm in length, 1921mm in width, and 1624mm in height, with a wheelbase of 2890mm. Powertrain: The 2021 Model Y features a front suspension with a double-wishbone independent suspension and a rear suspension with a multi-link independent suspension. It is equipped with a front induction asynchronous motor and a rear permanent magnet synchronous motor. The front motor delivers a maximum power of 137kW and a maximum torque of 219Nm, while the rear motor provides a maximum power of 180kW and a maximum torque of 326Nm, paired with a single-speed fixed gear ratio transmission.

Where Can I Register for Subject 4?

Subject 4 is generally taken at the local vehicle management office or at a location designated by the vehicle management office. Below is relevant information about Subject 4: Introduction to Subject 4 Exam: Subject 4, also known as the Subject 4 theory test, is part of the motor vehicle driver's license assessment. The Subject 3 test is divided into two parts: besides the road test, a safety and civilization knowledge test, commonly referred to as Subject 4, is added to assess driving ethics. The test paper consists of 50 questions, primarily in the form of case studies, images, and animations. Number of Attempts for Subject 4 Exam: There is no limit to the number of attempts for the Subject 4 exam. As long as it is within the validity period, you can keep scheduling the exam. Subject 4 can only be taken after passing the Subject 3 road driving skills test. Those who fail the exam have one opportunity on the same day to directly apply for a retake, and the previously passed road driving skills test results remain valid.
